Petunia (Wave Purple) is a revolutionary spreading petunia that transformed annual bedding plant horticulture — the original Wave series variety that introduced trailing, ground-covering habit to petunias. Growing just 4–6 inches tall but spreading 3–4 feet wide, Wave Purple cascades dramatically from hanging baskets, window boxes, and container edges, or covers ground as a living mulch in beds. The intense purple blooms are produced in extraordinary abundance from late spring through frost, requiring no deadheading. Wave petunias are self-cleaning — spent blooms drop automatically — and are significantly more weather-tolerant than standard petunias. The vigorous, spreading habit makes single plants a spectacular display all season long.
Plant Wave Purple after all frost danger has passed in full sun in well-drained soil or quality container mix. Space plants 18–24 inches apart for ground cover use, or one plant per 12-inch hanging basket. Water consistently — Wave petunias in containers may need daily watering in hot weather. Fertilize every 7–10 days with a high-potassium liquid fertilizer (such as tomato feed) — Wave petunias are heavy feeders and underfeeding causes pale, spindly growth. No deadheading required — the self-cleaning habit is one of their defining features. If plants become leggy mid-season, cut back by one-third and apply fertilizer for a rapid rebound and fresh flush of bloom. Protect from strong winds in hanging baskets as the sprawling stems are somewhat brittle.
